What works in increasing engagement in energy tariff choices

Reports, plans and updates

Over the last three years, Ofgem has produced world class evidence which proves that customers who haven’t switched energy tariff for many years can be prompted to do so following simple, well designed letters and emails. 

This robust research programme has included ten trials and extensive qualitative research.

This report brings together the results of these trials for the first time. The report looks across the extensive evidence generated by the trials to draw insights about what works in changing customer behaviour.
